The application discloses a low-voltage pulsating electric composite flexible cutting processing method, which mainly characterized by: using low voltage instead of traditional high voltage discharge, lower than the plasma maintaining voltage can still carry out the electric discharge machining and the electric discharge process not only exists the electric arc discharge but also accompanies the spark discharge, effectively shortens the gap discharge distance, and greatly reduces the stray corrosion range that may be produced in the electrolytic processing process; using the intermittent electric field, the periodicity of the plasma discharge and the electrolytic reaction can be controlled; using the alkaline solution as the electrolyte, the alkaline solution has good ion conductivity, can guarantee the stable electric field and current, can promote the dissolution and removal of the workpiece material through the chemical action of the alkaline solution; using the tube electrode rotating mode, the narrow gap energy field quasi-equilibrium state pulsating effect is realized and the chip removal is strengthened by the continuous rotation of the tube electrode, the high-pressure internal liquid and the pulse power supply (referred to as "machine-liquid-electricity") coupling effect, the low-voltage mixed plasma pulsating thermal effect, fluid effect and electrolytic reaction are organically combined, and high efficiency, low cost and high quality are realized for the machining of the difficult-to-machine material large-thickness straight surface parts.

The invention relates in one aspect to a pressure sensor for measuring fluid pressure. The pressure sensor includes a detection chamber having a thermal sensor disposed therein. The thermal sensor includes a heating element for providing a thermal field and a sensing device for detecting a temperature response of the thermal sensor. The heating element is designed to be triggered in an oscillating manner at at least one frequency. The pressure of the fluid can be determined based on the temperature response of the thermal sensor. The thermal sensor is positioned on a carrier film that is held by the carrier structure and extends over the cavity. Furthermore, a hole is present which enables a pressure equalization between the cavity and the inner region of the detection chamber. The invention relates, in other aspects, to a method for measuring the pressure of a fluid and to the use of a pressure sensor according to the invention for monitoring.
